Nervous about separating fuel lines...

Hi All, I'm in the middle to attempting to change my valve cover gaskets and the CCV/PCV. The dealer sold me several other gaskets that require the intake manifold to be removed.

First of all I can't get the electric boxes off of the fuel injectors so I can't get the valve covers off. I was thinking about just taking off the intake manifold without separating the fuel lines. The bolts that hold it in place are pretty easy to reach with everything on it. Would gas spray everywhere if I did that? I'm just very nervous about separating the fuel lines.

To get the wire boxes off you first need to (m)

unclip the injectors from the connectors, see those little U shaped shiny metal clips, it's a PITA to get them off if you haven't done it before.
It is easier to unbolt the intake but you should first blow out all of the dirt so it doesn't fall down into the heads when you lift off the intake. You will still need to unhook the fuel line in the back corner of the engine to get the intake out of the way. Release any pressure in the tank first, then push the fuel line and the metal fuel line together, while together push the black clip in (hold it in), then pull both apart. Put a rag under the line to collect the fuel that will come out.

LOL, that the next mod, should be able to fly then

You bet.........maybe I should powder coat it.

Thanks fellas. I'm giving it another shot but...

I thought this would be easy since I've previously replaced the water pump, thermostat and struts (and a host of other things) but this one is much harder to figure out since there are so many more tiny parts that are difficult to get to. If I can't get it done this week I may have to flat bed it to the dealer with a bag of parts and let them finish the job.

How much do think they'll charge for labor for the CCV and valve cover gaskets?

Maybe 2 grand, does that motivate U to DIY?

There's 10 nuts that hold the intake manifold on(m

It's just stuck, gaskets to the heads. Give it a whack on both the left and right sides with a rubber mallet or a "BMW certified 2x4".
I assume you will be replacing the 4 intake gaskets, the profile gaskets for the CCV and maybe the throttle body(TB) and it's adapter plate.
Clean out the oil inside the bottom of the intake, you should remove the TB and note how the tube from the rear to the front clips into place before you remove it.
Look at the back side of the intake valves, any carbon build up? Any on the runners?
Get a bunch of 6mm x 1.0 x 25 bolts to replace all of the torx head bolts, much easier to deal with if you ever need to remove the CCV again without removing the intake manifold.
Does the valley pan gasket or the 2 coolant tubes show any signs of leaking?

LOL.....is this positive or negative motivation?

Positive, it got him to continue the job.

Re: There's 10 nuts that hold the intake manifold on(m

Jim got a question about that tube. When the intake is lifted off does this tube just fall of the back of the intake? and how is it put back on? do u have to put it in the same time the intake is being put back on the motor?

You could do it that way or what I usually do is (

Pull the last section of plastic tubing off and stick it on the CCV fitting. Bolt the CCV onto the back of the IM. Hold the metal tube up and slide the plastic tube in while you move the IM forward. 3 hands would make it easier.

Re: You could do it that way or what I usually do is (

oh man this valley pan and ccv job is gonna suck big time. I'm gonna try and hold out a month for the better weather. If i try now ill just break everything cause ill be freezing and rushing everything. My garage is taken up by my e30 that's in pieces and sitting on skates. And my driveway is a giant incline so i cant roll the e30 out. doooh
